This study compared black and white children on the Behavior Problem Checklist. Data on 1,162 white and 614 black children were obtained from school records and from teachers and were analyzed using multiple regression analysis of variance. Blacks were judged to have a greater frequency of behavior disorders than whites. A number of interactions of race with other variables were found, and their meanings were discussed. 相似文献

Policy recommendations that adolescents supplement their experience in school with experience in the workplace have been made in the absence of objective data on the nature of most adolescents' activity on the job. This paper presents a coding system for chronicling a variety of microbehaviors in sequence, as they occur, in adolescent job environments. Three elements of each of approximately 100 behaviors performed by a targeted teenage worker are recorded by an on-site observer who enters appropriate code numbers into a portable event recorder: (1) the social context of the behavior; (2) the character of the behavior; and (3) the duration and concomitants of the behavior, when appropriate. Each of 97 working teenagers was observed continuously over a two hour period on the job. Interobserver agreement on the coding of worker behaviors and the social contexts in which they occurred averaged .86 and .97, respectively. In addition to its applicability in research on the effects of working on adolescent development, information obtained using the code can be helpful in the evaluation of youth employment programs, the vocational counseling of adolescents, and the validation of subjective worker reports of job attributes. 相似文献

Preschool and many older children often have difficulty understanding who carries out the complement action (e.g., to go in sentences such asMary promised John to go; this is so, even though they easily understand this information in sentences such asJohn told Mary to go. C. Chomsky (1969) proposed that children's errors arise from the overgeneral application of a purely structural Minimal Distance Principle. Maratsos (1974), however, hypothesized that children err by overgeneralizing a different principle which he called the Semantic Role Principle. According to this principle, the Goal-Recipient of the spoken message, not the closest noun phrase, is understood as the person who carries out the act referred to by the infinitival complement. The two studies reported here were designed to determine which of these principles children use. Preschool children were taught to understand a specially designed novel construction. The children then acted out sentences containing related but novel uses of the construction such that they would respond differentially according to which interpretive principle they used. The results strongly favored the Semantic Role Principle, rather than the MDP described by Chomsky (1969), or a related, more complex MDP described by Rosenbaum (1967). It is further discussed how children's formulation of the Semantic Role Principle, rather than the MDP, might arise from their prior analyses of related constructions, such as the imperative construction, rather than following from an innate preference, as suggested in Maratsos (1974).This research was supported by the NICHD under Grant #5 R01 HD09112-02 given to M. P. Maratsos. 相似文献

Multifactorial assessment of bulimia nervosa 总被引:1,自引:0,他引:1
D L Tobin C Johnson S Steinberg M Staats A B Dennis 《Journal of abnormal psychology》1991,100(1):14-21
We investigated a multifactorial approach to the assessment of bulimia nervosa by means of hierarchical factor analysis. Two hundred forty-five bulimia nervosa patients and 68 patients with either anorexia nervosa or eating disorders not otherwise specified were administered a self-report battery that was organized into 21 dimensions relevant to eating disorder patients. When dimensions from this battery were subjected to hierarchical factor analysis, support for bulimia nervosa as a unique diagnostic category was obtained. However, the emergence of 3 secondary factors and 6 primary factors suggests that bulimia nervosa can also be described more complexly. The emergence of a multifactorial model of bulimia nervosa that incorporates several existing undimensional models suggests the potential for both divergent and complicated clinical presentation in bulimia nervosa patients. 相似文献

Data were obtained from 46 mother-child pairs from the Child Behavior Institute (CBI) at the University of Tennessee. These
mother-child dyads were referred for psychological help because of the child’s aversive behavior. Child-parent interactions
were quantified using a multi-code, observational system. Correlational and multiple regression analyses (stepwise) were conducted
to find the best predictor of the child’s aversive behavior. Results showed that the child’s aversive behavior was significantly
correlated with the mother’s aversive, indiscriminate, and compliance behaviors. The regression analysis showed mother’s aversive
behavior to be the best predictor of the child’s aversive behavior. Moreover, our results seem to point out that the compliance
hypothesis is more effective in predicting child aversive behavior than the predictability hypotheses. It appears that since
the two hypotheses are dealing with similar processes, they are more complementary than oppositional.
This study used data collected by the Child Behavior Institute (CBI) at the University of Tennessee, Knoxville. The authors

To determine whether poor sleepers have a unique personality constellation significantly different from that of good sleepers, a sample of 162 emotionally disturbed adolescent poor sleepers was compared to a sample of 153 emotionally disturbed adolescent good sleepers on standardized personality instruments. Poor sleepers were found to have a high incidence of neurotic psychopathology with personality patterns characterized by depression, fearfulness, inhibition, anxiety, and rumination. In contrast, good sleepers showed quasi healthy and/or characterological patterns. While this study does not resolve cause and effect relationships, it does establish a highly significant relationship between neuroticism and sleep disturbance for adolescent boys and girls, and also demonstrates a similarity of personality dynamics and patterns between adult and adolescent samples of patients with sleep disturbances. 相似文献

Marvin A. Steinberg Community Mental Health Specialist 《Journal of School Psychology》1976,14(4):355-361
A child-and-family oriented community mental health center of necessity is concerned with the manner in which the school system in its community is providing for the psychological, social, and emotional development of children. Fortunately, over the last decade, the number of school systems that are aware of their responsibility in this regard has greatly increased, and many affluent and enlightened school systems have moved to develop extensive pupil personnel services, functioning in many ways as in-house mental health programs. Where there are mental health providers both within the community and within the school system, however, problems may develop such as professional competition, overlapping functions, and differences with regard to how mental health problems are best dealt with. This paper will examine the relationship of a town-supported mental health program and the town's public school system. Highlighted will be the variety of problems which develop, including those mentioned above, and strategies adopted to resolve the problems. 相似文献
